Abstract
Stud connectors we are now using are welded verticaly to steel members and they resist, to the shear force by dowel action. We thought stud connectors can work more effectively by welded inclined to steel members because they resist directly to the shear force by their axial force . Here we examined the basic behavier of inclined studs by experiments and FEM analysis. And we obtained the results that positively inclined studs have higher stiffness and strength compared to vertical studs. If we use inclined studs where the shear force acts in the constant direction, the studs can work very effectively.
